To all 'wiz-om t may concern:

Be it known that I, ANDREW W. LIVING- sToN, a citizen of the UnitedStates, residing at Oakland, in the county'of Alameda and State ofCalifornia, vhave invented certain new and useful Improvements in Tires,of which the following is a specification.

This invention relates to tire protectors and thel principal object ofthe same is to provide a protector which will iit between the iniatingtube'and the outer protecting casing of the tire so that the inlatingtube will be protected frompunctures.

It is4 also desired to produce a protector which may be readily removedfrom one tire to another so'that when the outer casing is worn out theprotector may be easily removed, and a new outer casing provided.

This invention is illustrated in the accompanying drawings, whereinFigure 1 is a viewy of a wheel provided with the improved protector`shown partially in side elevation, and partially in section. Fig. 2 isa perspective view of a section of the outer member of the protector.Fig. 3 is a fragmentary sectional view through a tire provided with theprotector. Fig. 4 is a transverse sectional view through a tire providedwith a protector. Fig. 5 is a fragmentary side elevation of a tireshowing the meeting tallic strip extending along' the tread portion ofthe tire. Fig. 6 is a sectional View along the line 6 6 of Fig. 5:

Referring'to the accompanying drawings by numerals it will be seen thatthis invention is used with a tire having the qinner inating tube 10 andthe outer protecting casing 11 which is secured to the wheel rim bymeans of the bolt 12. A metallic band 13 incloses the tread portion ofthe inner tube 10 and isprovided with rolled sides 14 the purpose ofwhich will be hereinafter brought out. A fabric strip 15 is carried by-the band 13 and carries a number of blocks 13 which support. the treadportion of the outer casing 11 thus holding the casing in spacedrelation to the inlating tube. The free ends of the band 13 areoverlapped as shown in Fig. 5, and are each provided with a strip 17having outstanding flanges 1S. These ianges 18 limit the contraction ofthe band, thus permitting the band to accomends of the me-Y vided withmodate itself to the size of the inner tube I and to permit the innertube to take up anyl jolts and jars due to going over rough roads. Thisgives the tire all the resiliency of a pneumatic tire while, at the sametime the band protects the tread-portion of the inner tube frompunctures. Side bands 19 are positioned in the casing and extend alongthe sides of the casing. The inner ends of the band 19 are rolledinwardly to form the anges 2O which overhang the curved sides of theband 13, thus'preventing nails or other objects from passing between thebands. ItV should be noted that these over-hanging portions of the bandsare in spaced relation thus preventing the bands from interfering withthe free contraction and expansion of the tire. The bands 19 passbetween the contacting edges 21 of the casing and extend for avshortdistance between the casing, and the rim 22. The bolts 12 pass throughthe bands 19 so that when the casing is clamped to the rim the bands 19will besecurely held against any movevment.' It will thus be seen thatit is impossible for the bands 19 to work loose and by rubbing againstthe inner tube wear the same. Bands 23 are placed to each side of thecasing and clamping plates 24 are secured to the sides of the rim andoverlap the bands 23 so that the bolts 12 which hold the bands 19 inplace may be used for holding the rin s 24 also.

When' using this device, the band 13 is placed in the casing and theinflated tube lnserted. rlhe side bands are then inserted with theflanges 20 overhangin the rolled sides 14. The bands 23 are ien placedupon the tire and the plates 2,4 secured to the rim by means of the bolt12. The tire will be held in place and the bands 19 prevented frommovement. When it is desired to remove this protector, all that isnecessary is to remove the tire from the rim, and withdraw the sidetread bands 13. f

What is claimed is A tire comprising an outer casing, an inner tubing, ametallic band surrounding the tread portion of said inner tubing andprooutwardly curved side portions, the end portions of said band beingoverlapped and carrying ribs to-limitthe overbands 19 and the 2 weoneslapping movementof the band, blocks in place and securing said casing toa wheel mounted upon said band and holding the rim. 10 same in spacedrelation to the tread portion n testimony whereof I ax my signature ofsaid casing, reinforcing stri s for the side in 'presence of twowitnesses.
